When does revamping pay off?

With projects in many PV markets aging past the 10-year mark – with major leaps in technology having occurred in that time – revamping is a popular topic among asset owners. pv magazine spoke with Asier Ukar, general manager of the Spanish subsidiary of German engineering company PI Berlin, to uncover the benefits of revamping PV projects with new components and also to examine the challenges and risks involved.

pv magazine Roundtables Europe live coverage

Welcome to the first day of the pv magazine Roundtable Europe event! We have a packed two-day schedule planned for you comprising four cornerstone issues that will define the industry as it cements itself as a key pillar of the continent’s energy transition: Quality, Asset Management, Sustainability and Made in Europe, and the Innovation Hub: Hydrogen, battery storage, and e-mobility.

A repair tape for cracked backsheets

Backsheet failures have plagued the industry, causing hefty financial burdens to many asset owners. DuPont has launched a product it says allows for easy repair of modules.

Module testing reveals increase in mechanical failures

Last week, testing specialists PV Evolution Labs launched its latest Module Reliability Scorecard, which names more than 100 products from 26 manufacturers as top performers, after being put through their paces in extensive lab testing. This year’s scorecard reveals an increase in modules seeing at least one failure during the testing procedure, with newly added mechanical stress procedures causing the greatest number of failures.

AI identifies a $14bn solar problem

How do you know when an inverter or module is under-performing? Monitoring services should shed light on problems but AI-driven digital asset manager Raycatch says much information is hidden behind a wall of “noise.” Breaking that wall with advanced data analysis could unlock billions of cost savings.

From power to energy rating, for a better choice of PV module

A new report published by the International Energy Agency’s Photovoltaic Power Systems Program (IEA PVPS) outlines the need for PV module standards and testing to focus on ‘energy rating’ – an estimate of actual performance in a variety of climate conditions, rather than nominal power output or efficiency. The report finds that the IEC and other standards bodies are already beginning to make encouraging moves in this direction, but more work, and more data, are needed to make the most out of this approach.

DNV GL’s Battery Scorecard 2020 sees manufacturers focus on LFP and fire safety

The third annual scorecard published by the consultant has tested 22 batteries with different chemistries for cycling stability and temperature-dependent behaviour and identified significant product trends.

Shifting directions in PV mounting solutions

Solar photovoltaic mounting firm, Premium Mounting Technologies (PMT), was founded by industry veteran Peter Grass in 2012. The company is now shifting gears – in leadership and technologies. Sitting down with the company’s installation partner Solartechnik Dresden’s CEO, Steffen Hesch, the two discussed new business models and changes in solar.

New three-step module testing from TÜV Rheinland

German standards body TÜV Rheinland is introducing a new testing and certification program for pv modules. The program incorporates component specific tests and ongoing, random testing of running production lines. Hanwha Q Cells assisted in the development of the program, and this week announced it is the first manufacturer to receive the new Quality Control PV Certification.

pv magazine video: How quality can lower solar risk and insurance rates

This year’s pv magazine Quality Roundtable USA looked at extreme weather, and how resiliency can be built through modern O&M. Representatives from DuPont, Stäubli, Nextracker and RETC took to the virtual stage to discuss weather-related damages, and how to harness quality materials and workmanship to industry’s advantage, particularly when it comes to insurers. Ariel Re and NovaSource, meanwhile, looked at issues like risk management insurance solutions and asset stabilization. Case studies and presentations on the field performance of PV modules, and extreme hail and fire, were also included.
